F0 all whom it may concern:

Be it "known that l, SULTAN Scnosn- Bacon, ajcitizen of the United States, resid ing at Pittsburgh, in the county of Allegheny and-fitate of Pennsylvania, have invented a new and useful Electric Steam- Generator/of which the following is a speeification. I

The present invention relates to improvements in electric steam generators, the primary object of the invention being the provision of a boiler or tank for containing Water and steam. generated therefrom, in combination with a conduit mounted Within the same and norn'lally submerged ivitlr in the water, said conduit being her1netically sealed so that the conductor wires carried therein and led from any source. of electrical energy will not he brought in contact. with the Water, there being a plurality of pairs of spaced electrodes carried in spaced relation throughout the length of the con-- duit, said electrodes projecting into the Water and connected in parallel to the conductors within the conduit.

A further object of the present invention is a novel form of electrode carrying plug held tightly within apertures formed with in the wall of the conduit, so as to permitthe ready rernovalnind renewal of the electrodes, and at the time form a tight sealto prevent the leakage of the water into the conduit; 3

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the cornbination and arrangementof parts and in the details of construction hereinafter described and claimed, it being under. end that changes in the precise eznht'idiinent of invention herein disclosed can be made within the scope of what is claimed without departing from the spirit'of the invention.

In the drawings Figure l is a perspective View of a generator, a-portion of the same being broken away to show the disposition of the heating element, therevvithin. Fig, 2 is a cross section through the end-of the boiler showing the heating element in end elevation. Fig. 3 is a longitudinal section of the forward portion of the boiler with portions of the heating element in elevation. Fig. 4t is a cross section taken on line el-d oi" 5. Fig. 5 is a longitudinal section through the conduit and electrode carrying plug. Fig. 6 1s a perspective View of one of the plug retaining clamps. Fig. 7 is a diagram of the electrical circuit.

Referring to the drawings, the numeral 1 designates the boiler tank which has disposel therein and supported in any desired nmnner, the coiled conduit- 2 Which projects extcriorly ot' the boiler as at 3 and provides a. l'ierznetical conduit. for the reception and retention of the conductors and which receive their current from any source 6 of electrical energy.

lZ-renclied oil from the respective conductors 4 and 5 at desired intervals throughout the length of the conduit are the branch conductor T and 8, respectively, which are provided with the bare terminals 9 and. 19, rcspectiv; to tit 'Wltlllll the clamps ll, carried by the respective terminal carrying illllgf'i l2 and 13 respectively. These termi nine arc'insulated from the main plug l t, which is titled snugly within the apertures 2 of the condi'sit 2 by means oi" the hushings l5 and l6, respectiv i of insulznfiion.

Each .ne of the respective plugs 12 and. 1.3 is provided with the threaded stems l7 and lo respectively, to which are rernovably attached the electrodes 19 and {*0 respectively. These electrodes are preferably n'azg. of carbon, though any other material i'nay he used that will. produce the desired gap to he closed by the intervening Water, so that. the current of electricity supplied from the parallel Ctllltttit'ilOl'S 4; and 5 will from the electrode, asfor instance 1 through the intervening Water to the electrode 20, thus producing suthcient heat to wins-e the generation of the steam.

r. Of

in order to retain the electrode plug 1% tightly within the apertur the conduit 2-, so that. there can he no lento age of the water into the conduihn retain iiig clip or clamp such as shown in F 6 preferably employed. This consists of a curved body of a slightly greater length then half of the circumference of the conduit and provided with the broad portion El, carrying the adjusting screw and clamp plate. 23, and the reduced term nal. 24. When in posit-ion the reduced terminal 24 restsupon the strip '25 of insulation ictween the ICSl'JQCtlVQ plugs 12 and l3 while the hotly portion extends partially around the conduit, so that the clamping plate null engage the conduit at a point diametrically opposite to the longitudinal center line of the plug 14.
